9d0afa2ab0 Remove out-of-memory test in QVarLengthArray.
No reason to keep this test. If an application is trying to allocate too
much memory it will fail, and its the users responsibility to provide
sane values and catch exceptions to recover.

53e6cb3ff6 Fix the gregorian date <-> julian day calculations in QDate
The old code is just plain wrong for negative julian days. Replaced
with plain math from The Calendar FAQ [1], which is correct for all
julian days, provided you use mathematical integer division (round to
negative infinity) rather than c++11 integer division (round to zero).

[1] http://www.tondering.dk/claus/cal/julperiod.php

While the conversion code works for up to around JD +/- (2^63/4), we
only use an int for the year in the API, so this patch limits minJd()
and maxJd() to 1 Jan (2^31) BC and 31 Dec (2^31-1) AD, respectively.

Note that while the new conversion code looks like it would be more
expensive than the old, gcc will in fact be able to optimize it to be
slightly faster (probably because x86 hardware implements round to
negative infinity, and so GCC manages to optimize floordiv to a single
instruction, compared to the three instuctions needed for operator/).

In the following test application, run with a release mode Qt and
redirecting stderr to /dev/null, I measured an improvement from
6.81s +/- 0.08s to 6.26s +/- 0.16s user time over five runs on an
otherwise idle x86_64 system.

int main(int, char *[])
{
    int year, month, day;
    qint64 jd;
    for (qint64 i = Q_INT64_C(-1048576) ; i < Q_INT64_C(1048576); ++i) {
        QDate::fromJulianDay(i).getDate(&year, &month, &day);
        jd = QDate(year, month, day).toJulianDay();
        qDebug() << jd << year << month << day;
    }
}

af437047a2 QMap - improve QMap stl-map ctor

We always enforce an insert here (unlike the insert call),

6e4d7bbb0b QMap 5.0 - keep track of leftmost node (BIC)
This suggestion keeps track of the most left node.
The point is that constBegin() becomes a lot faster.

That speeds up iteration a bit, and makes it O(1) to get the
first element. The penalty in insert and remove is very small.
On large trees it seems to be less than 1%.

It should be noticed that constBegin() is a very common hint
on my planned change to 5.1, and this opperation will without
this patch cost 2 x log N. One when the user calls the hint
with begin - and one where it is compared with begin.

Other std::maps has a very fast begin(). E.g
http://www.cplusplus.com/reference/stl/map/begin/
(begin with constant time)

Instead omit the whole tests when appropriate.

In particular:

- When Q_CC_HPACC is defined the tests fromStdString and toStdString are
crashing. Omit the tests in this configuration since the compiler is not
supported.

- Clean the localeAwareCompare() by removing the code where Q_OS_WIN is
defined but not Q_OS_WINCE. System and user locale cannot be set on
Q_OS_WIN other than Win CE and some code could never be reached.

bdc115d969 detach() safely in QVector::erase(), and update callers to not detach.
remove() can use non-detaching iterators internally before calling
erase(), which hasn't been exploited so far, so that the detach() in
erase() never actually detached. When using erase() from outside,
you can't do it legally without calling begin() or end() that detach()
before erase() is called.
Now remove() doesn't detach anymore, and detaching in erase() works.
With new tests that fail after changing only the erase() callers
and pass again after fixing erase().

da7111be51 QTextBoundaryFinder: Fix handling of break opportunities
Add BoundaryReason::BreakOpportunity flag that will be returned by the
boundaryReasons() when the boundary finder is at the break opportunity
position that might be not an item boundary.
This is the same as (StartWord || EndWord) in Grapheme and Sentence modes;
in Word and Line modes, BreakOpportunity flag might occur between the words
or in between of Line boundaries (e.g. in conjunction with SoftHyphen flag).
In other words, the text boundaries are always break opportunities, but not vice versa.

StartWord and EndWord flags has been deprecated by new StartOfItem and EndOfItem
flags which are not about the word boundaries only. In line breaking,
StartOfItem and EndOfItem are set for the mandatory breaks only.

6276427438 QString::append: add (const QChar*, int len) overload
Both insert and replace have this overload, so one reason to add it
to append(), too, is consistency. But I can also make good use of
this overload in the the new QStringList::join(QChar) overload, so
it's actually useful in its own right.

b6a4e66ffb test: Mark tst_qtextboundaryfinder::generateDataFromFile() with internal build
This function only makes sense on a developer build. In non
developer-builds you get:

  tst_qtextboundaryfinder.cpp:116:13:
    warning: ‘void generateDataFromFile(const QString&)’
    defined but not used [-Wunused-function]

20993adffd QSharedPointer: make QT_SHAREDPOINTER_TRACK_POINTERS work with QObjects
If setQObjectShared crashes because a QObject is tracked by two
different QSharedPointers, we lose the debug feature offered by #defining
QT_SHAREDPOINTER_TRACK_POINTERS, as the check done by this define
happens after the setQObjectShared call.

Therefore, move setQObjectShared after the internalSafetyCheckAdd call.

This is actually a noop change in 5.0, as setQObjectShared does nothing.
However it prevents a bug in case the Qt 4 behaviour is brought back
in some later version.

f29896840c Handle invalid dates properly for QDataStream versions < 5.
In Qt 5, when streaming an invalid QDate using a QDataStream version
earlier than Qt_5_0, QDate.jd is written and read as 0, which is an
invalid julian day for Qt versions earlier than 5.0. For Qt 5.0
however, 0 is a valid julian day, so when comparing a deserialised
invalid date (read using a QDataStream version < Qt_5_0) against a
default-constructed invalid date, they won't compare equal when they
should.

09dd19df5c Do not consider sign in qIsNull.
The current implementation of qIsNull only returns true if the value is
positive zero. This behaviour is not useful for use cases like
QPointF::isNull, where QPointF(-0, -0).isNull() will return false.
There doesn't seem to be a reason why the function exhibits this
behaviour (-0.0 is not accounted for in the unit tests), and for the
case of QSizeF::scale it causes a bug: qIsNull is used to check for
division by 0.0 before it proceeds, which fails in the case of -0.0.

3a7b6a74a8 Disregard milliseconds in QTime::secsTo().
"The documentation states that "secsTo() does not take into account any
milliseconds", however, this is not the case. Given times 12:30:01.500
and 12:30:02.400 secsTo returns 0. If milliseconds are not taken into
account, I would expect this to return 1 (i.e. interprets the times as
12:30:01 and 12:30:02 thus truncating the milliseconds)."

Note that tests were also written for QDateTime::secsTo(), as it uses
QTime::secsTo internally. This addresses Javier's issue in the
comments of QTBUG-9304.

718a2251be Serialise QDateTime as UTC and timeSpec() instead of private spec.
QDateTime currently serialises its private Spec enum. If a user was to
deserialise the individual components of a QDateTime separately, the
resulting timeSpec may be invalid when cast to the Qt::TimeSpec enum.

E.g.:

QDateTime dateTime(QDate(2012, 8, 14), QTime(8, 0, 0), Qt::UTC);
// ... serialise
// ... deserialise date, time, spec separately.
// spec == 2, the value of QDateTimePrivate::UTC.
// spec != UTC, will be set to LocalUnknown.
QDateTime deserialised(date, time, spec);

This patch serialises QDateTime objects in UTC and the value of
timeSpec() as opposed to QDateTimePrivate's spec. This changes the
serialisation behaviour of QDateTime for version 13 of QDataStream.
